Banach
Stefan. 1892-1945. Polish mathematician who founded modern functional
analysis.

"A
mathematician
is a person who can find analogies
between theorems,
a better mathematician
is one who can see analogies
between proofs
and
the best mathematician
can notice analogies
between theories.
One can imagine that
the ultimate mathematician
is one
who can see analogies
between analogies."

"Mathematics is the most beautiful and most powerful creation of the
human spirit."
